Returns true
if yield
would execute a block in the current context. The iterator?
form is mildly deprecated.
def try if block_given? yield else "no block" end end try #=> "no block" try { "hello" } #=> "hello" try do "hello" end #=> "hello"
Returns current status of GC
stress mode.
Updates the GC
stress mode.
When stress mode is enabled, the GC
is invoked at every GC
opportunity: all memory and object allocations.
Enabling stress mode will degrade performance, it is only for debugging.
flag can be true, false, or a fixnum bit-ORed following flags.
0x01:: no major GC 0x02:: no immediate sweep 0x04:: full mark after malloc/calloc/realloc

The Kernel#require
from before RubyGems was loaded.
Shortcut for defining multiple delegator methods, but with no provision for using a different name. The following two code samples have the same effect:
def_delegators :@records, :size, :<<, :map def_delegator :@records, :size def_delegator :@records, :<< def_delegator :@records, :map
Define method
as delegator instance method with an optional alias name ali
. Method
calls to ali
will be delegated to accessor.method
.
class MyQueue extend Forwardable attr_reader :queue def initialize @queue = [] end def_delegator :@queue, :push, :mypush end q = MyQueue.new q.mypush 42 q.queue #=> [42] q.push 23 #=> NoMethodError
Called with encoding
when the YAML stream starts. This method is called once per stream. A stream may contain multiple documents.
See the constants in Psych::Parser
for the possible values of encoding
.
Sends a POST request to the path
.
Returns the response as a Net::HTTPResponse
object.
When called with a block, the block is passed an HTTPResponse
object. The body of that response will not have been read yet; the block can process it using HTTPResponse#read_body
, if desired.
Returns the response.
This method never raises Net::* exceptions.
# example response = http.request_post('/cgi-bin/nice.rb', 'datadatadata...') p response.status puts response.body # body is already read in this case # using block http.request_post('/cgi-bin/nice.rb', 'datadatadata...') {|response| p response.status p response['content-type'] response.read_body do |str| # read body now print str end }

Return a progress reporter object chosen from the current verbosity.
